AUXILIARY FEEDING DEVICE FOR INTERNAL COMBUSTION ENGINES Filed July 15,1929 Qwtwwtoo -Pat'ented Apr. 29, 1930 UNITED: sures JEAN B.BERGOUGNOUX, 01 LOS ANGELES, CALIFORNIA AUXILIARY FEEDING DEVICE FOR INTEBNAL-COMBUSTION ENGINES Application filed July 15, 1989. Serial No.378,506.

This invention is an improvement on my prior Patent #1,299,817, patentedApril 8, 1919, for an Auxiliary feeding device for internal combustionengines and relates to the feeding of engines of the internal combustiontype and more particularly to an auxiliary device that is connected toand discharges a suitable vaporinto the intake manifold of a gasolineengine. The obj ectsvI have in view are to provide a feeding device ofthis character that is both simple in construction and easy tomanipulate'and is also one that comprises few parts so that it may beeconomically manufactured and can be sold for a moderate price. It isalso an object of my invention to provide suitable means whereby thequantity of vapor discharged from the device may be regulated oradjusted to a nicety and may be turned on or cut off whenever desired.Owing to the construction and arran ement of the parts of my device, Iam ena led to attain divers results from its operation. For example, thevapor discharged into the manifold by my device may be charged withwater or gasoline for the purpose of modifying the gaseous mixture fromthe carburetor, or for the purpose -of cleaning the pistons andcylinders, etc.,.

the vapor may be charged with kerosene or a carbon removing compound,infact, any suitable liquid may be placed in the reservoir of my deviceand the vaporized mixture fed to the manifold.

The improvement consists in attaching a valve to the original devicewhich valve'is operated by the foot throttle or accelerator on theautomobile so that the flow and volume of the mixture is controlledthereby, and the air is fed through the oil or other liquid in suchamounts and volume as will produce the most eflicient mixture of theliquid and air at all speeds. Heretofore at high engine speeds t e oilor other liquid used was not groperly fed in the original device andother the device operatively connected to the car bureter andaccelerator.

Figure 2 is a sectional view of said device.

7 My lnvention comprises a cylindrical chamber or reservoir 1 of glassor other suitable vehicle part adjacent the engine. The lower ca 3 isprovided with a radially extending en argement 7 and a centrallypositioned threaded opening 8. A tube 9 threaded at both ends, isthreaded into the boss 4 and opening 8 serving to tightly hold the capsin lace relative to the chamber 1, said tube eing provided with atransverse bore 10 adjacent its upper edge, for a purpose to behereinafter described. The enlargement 7 of the cap 3 has formed thereinat the outer end thereof, a threaded opening 11, in communication with atransverse chamber 12 having a passage 13 open to the atmosphere. On theother side of the chamber 12 is a passage 14, terminating in a threadedportion opening into the reservoir 1. Fitted into said threaded portionis one end of a U-shaped tube 15, the other end be; ing open and spaceda short distance from thebottom of the reservoir 1, the bight portion ofthe U-tube being positioned a-distance above the normal level of thefluid in the reservoir. A plug 16 provided with a threaded, bore 17 anda threaded, portion 18 of reduced diameter is fitted into the opening11, and has positioned in said bore 17 the stem of a needle valve 19,the tapered portion of which is adapted-to abut vor closefin varyingdegrees the entrance to-the passage 14 as clearly shown in Figure 2. Theother end of the needle valve 19 has rigidly secured thereto by means ofthe set screw 20,-alever 21 provided with an opening 22 for thereception of a link therein. I

Threaded in the upper portion of the boss 4-is an-elbow 23 which hasattachedat its other end, one end of a pipeline 24, the other end ofwhich is attached to the air intake portion of a carbureter 25, seeFigure 1.

Attached to the lever 26 of the throt le in the intake manifold 25' is alink 27operated by the'accelerator 28. An additiona-lllink 29 connectsthe lever 26 with the lever 21 operating the needle "alve 19, thereservoir.,, being mounted in any suitable position, as shown.

The linkage connections and position of the needle valve 19 are suchthat the position of the throttle governs the opening controlled by theneedlevalve 19, and consequently the quality of the mixture,i. e., at

high engine speeds, the throttle" is wide open, the needle valve wouldbe moved back and the I maximum amount of air allowed to flow throughthe pass e 14 into the-tube 15 and throu h the liqui in the reservoir.as indicated y the arrows in Figure 2, vaporizing the same into anefficient mixture and then passed through the pipe line 24 to the intakeportion of the carbureter.

The cap 2 is additionally provided with a 25 threaded opening receivingtherein a filler plug 31.

It is apparent that the above described device is susceptible of variouschanges within the scope of the appended claims and while 30 the deviceshown is a preferred embodiment thereof, I do not desire to be limitedthereto. Having thus described my invention, what I claim as new anddesire to secure by Letters Patent is 1. An auxiliary feeding device forinternal fluid receiving reservoir, upper and lower cap plates fittedthereon, a hollow interiorly threaded boss centrally formed on saidupper cap plate, a threaded recess in said lower cap plate, a tubularmember interconnecting said cap plates and fitted within said boss andsaid recess and formed with a transverse port adjacent its upper end, achamber open to the atmosphere formed in said lower cap plate, an airpassage connecting said chamber with the interior of said reservoir,said air passage forming means to eject air at the bottom of thereservoir so that the same may rise through the liquid, and means tovary the amount of air entering said reservoir.

2. The structure specified in claim 1. said first mentioned meanscomprising a U-shaped tube having one end thereof fitting into saidpassage and the other end terminating short of the bottom of saidreservoir, the bight portion of the U-tube being positioned a distanceabove the normal level of the fluid in the reservoir. 7 3. The structurespecified in claim 1, said last mentioned means comprising a needlevalve fitted in said lower cap plate the tapered portion of whichextends into said chamber therein and which is adapted to vary theopening of said passage, a lever rigidly concombustion enginescomprising a cylindrical nected to saidneedle valve exteriorly of saidcap late, a link connectin the t rottle lever in the inta e manifold ofthe engine, whereby movement of said throttle by a foot acceleratorcauses a corresponding movement of said needle valve to vary the amountof airentering said reser- VOlrwhereof I afiix'my si ature.
